Diatomaceous earth is a naturally occurring element in nature. It is soft, siliceous sedimentary rock that can be crumbled into a fine, white-ish powder. It can also come from fossilized diatoms, which are hard-shelled micro-algae, which have sucked silica out of the water making their fossils siliceous as well. So if you’re wondering where diatomaceous earth is found, it is found in nature.

2 Types of Diatomaceous Earth

There are two types of diatomaceous earth: food-grade and industrial-grade. 

While industrial-grade diatomaceous earth is used in filtration, abrasives, and pest control, it is not safe for consumption. 

Food-grade diatomaceous earth is noted as safe for both human and animal consumption, and is often used in food storage and agriculture. Some medical sites suggest that it helps with constipation or other digestive issues. It is best to consult a medical professional prior to taking any supplements such as diatomaceous earth.

While food-grade diatomaceous earth is considered safe for consumption and handling, it is important to avoid inhaling the fine dust, as it can irritate the lungs. Industrial-grade diatomaceous earth should be handled with care and used only for its intended purposes.

If you’re wondering how to use food-grade diatomaceous earth for pest control or how much diatomaceous earth for pest control, keep reading on, or jump ahead to our section 5 Diatomaceous Earth Application Tips. Food-grade diatomaceous earth is the best option if you are using diatomaceous earth for pest control.

4 Main Residential Uses of Diatomaceous Earth

There are four main residential uses of diatomaceous earth: food storage, health supplement, gardening, and pest control.

Food Storage: Because food-grade diatomaceous earth helps keep products dry and simultaneously can kill insects, it can be mixed with bulk dry storage of grains and legumes, for example, to prevent stored product pest infestations.

Health Supplement: Some people consume food-grade diatomaceous earth as a dietary supplement, claiming benefits such as improved digestion, detoxification, and enhanced skin, hair, and nail health. Again, we would recommend discussing health items with your doctor or medical professional.

Gardening: Diatomaceous earth can be used in gardens, especially food gardens. It benefits the soil condition in improving its structure and retaining moisture. It can also be helpful in killing some unwanted garden pests.

Due to folks’ limited knowledge of diatomaceous earth, we typically only recommend the use of diatomaceous earth as pest control in the yard or garden. Because it can cause respiratory issues and other conditions, we never recommend indoor use of diatomaceous earth as a pest control method.

However, diatomaceous earth for pest control as a natural insecticide is widely searched online and used fairly willy-nilly in our experience. Many will go overboard in the amount needed or don’t end up treating in the right area. Several develop rashes or respiratory conditions from using diatomaceous earth for bed bug control, or from using diatomaceous earth for flea control, or from using diatomaceous earth for mite control.

Pest Control: That said, the science behind using diatomaceous earth for pest control is that while it feels like sand or dirt to us, the tiny particles and grains of diatomaceous earth are actually jagged to tiny insects and so it cuts the insects, absorbs the oils and fats from their exoskeletons, which in turn causes them to dehydrate and die.

If you are wondering how to use diatomaceous earth for pest control: the short answer is, it is difficult. The longer answer is: diatomaceous earth is not a repellent or a bait, so it would skillfully need to be placed where insects are already traveling. Because insects have behavioral patterns that the common homeowner is not familiar with, it is always recommended to first have a discussion with a licensed and professional pest control expert.

Overall, diatomaceous earth is a versatile and eco-friendly product with a wide range of applications in pest control for gardens and yards, agriculture, and health.

Top 3 Reasons Why Diatomaceous Earth is Considered Effective Pest Control

Diatomaceous earth’s natural physical properties are unique in that it is soft to the human touch, but dangerous to itty bitty insects. The top three reasons why diatomaceous earth is considered effective pest control is due to physical abrasion, desiccation, and mechanical action. If you are wondering how to use diatomaceous earth for pest control or how diatomaceous earth kills bugs, this is the ‘how it works’ segment.

Physical Abrasion:  Diatomaceous earth is composed of tiny, sharp-edged particles. When insects crawl over the diatomaceous earth, these microscopic edges abrade their exoskeletons, which are the hard, protective outer layers of their bodies.

Desiccation: The sharp particles of diatomaceous earth also absorb the oils and fats from the insect’s exoskeleton. This action leads to the drying out, or desiccation, of the insect. Without these essential oils and fats, the insect loses its ability to retain moisture.

Mechanical Action: Chemical pesticides work well and are designed to attack insects’ nervous, immune, or other systems. Chemical pesticides always have to adapt over the years as it is possible for insects to slowly develop resistance to it.

Because diatomaceous earth is not a chemical, and because it is sharp and causes physical abrasion to the insects, insects cannot develop a resistance to diatomaceous earth. The physical nature of its action ensures that it remains effective over time.

2 Basic Safety Measures with Diatomaceous Earth

Inhalation: Avoid inhaling any diatomaceous earth dust. Diatomaceous earth, as described above, is basically microscopic shards of glass. As such, this can be very damaging to your respiratory system. It is highly recommended to use a quality mask or respirator while applicating diatomaceous earth.

Use food-grade quality: In the first segment of this guide on diatomaceous earth, we discussed the difference between food-grade and industrial-grade diatomaceous earth. For residential use, only use food-grade diatomaceous earth. Food-grade diatomaceous earth is the best option if you are using diatomaceous earth for pest control.

I never recommend using diatomaceous earth inside the house because air conditioning systems can kick it up into the air and there is the constant risk of respiratory infection and issues with diatomaceous earth.

If you have pets or children, again, I would never recommend using diatomaceous earth inside the house. Pets have a tendency to lead with their noses and sniff around and we wouldn’t want them to have their airways clogged or have respiratory issues or infection either. They are our furry family.

5 Diatomaceous Earth Application Tips

Diatomaceous earth is widely approved for some crazy pest control strategies among homeowners, property managers, tenants, etc., when in reality, it is important to study up on all of the benefits and drawbacks associated with the product prior to use. When people hear the word “natural” they automatically think it is 100% safe, but too much of a good thing, overuse of a good thing, or incorrect use of a good thing, makes it no longer a good thing or 100% safe.

If you are wondering how to use diatomaceous earth for pest control or how to apply diatomaceous earth for pest control, check out these 5 diatomaceous earth application tips:

  1. Only apply in dry environments. Diatomaceous earth can is most effective in dry environments. Moisture, like rain, can reduce its efficacy.
  2. Treat outside the house. As long as it’s dry out, diatomaceous earth can be an effective pest control method to use outside. It is naturally occurring in nature outside, afterall, anyways.
  3. If it rains, reapply. The trouble with natural products is the necessity to reapply upon weather and general time. If ever you are using peppermint oil to repel mice (link), vinegar to repel ants (link), or dawn dish soap and water to repel fall invading pests (link), these products need reapplication with weather and time. Diatomaceous earth is the same.
  4. Treat the cracks and crevices. Diatomaceous earth is typically best used in small quantities. And if you must use it in the house, I would only recommend outdoor treatment, apply it to cracks and crevices only where air circulation is so minimal or virtually non-existent. Plus, pests can squeeze in cracks and crevices, so it serves as a double benefit.
  5. Use small amounts. A light dusting is sufficient. A heavy application is not only unnecessary, it can cause skin reactions and respiratory issues and infection.

If you are wondering how to use diatomaceous earth for pest control indoors, I typically do not recommend it, because the majority of the time people overuse and it negatively affects them and does not get rid of the pests. If you must use diatomaceous earth for pest control indoors, I would only recommend a tiny amount in the cracks and crevices where insects would come out from the walls.

Top 4 Pests Diatomaceous Earth is Effective Against

If you are wondering what pest does diatomaceous earth kill or what kind of insects does diatomaceous earth kill, the answer is: there are 4 main categories of pests we could ever recommend diatomaceous earth for. 

The package may say that diatomaceous earth kills a number of insects though. It is true that diatomaceous earth may kill many types of insects, but most infestations have a source and diatomaceous earth will not kill the source.

Therefore, we have developed a list of the top 4 pests diatomaceous earth is effective against.

  1. Chiggers in the yard
  2. Fleas outside
  3. Anthills
  4. Garden pests

Chiggers in the yard: If you are looking for a great article on how to treat and prevent chiggers in your yard, we suggest ours. It does describe how we would treat chiggers, but chiggers are so tiny, they can be difficult to treat with chemical product, unless effectively employed by a competent pest control technician.

Chiggers can easily be controlled and prevented by using diatomaceous earth in your yard. Simply sprinkle diatomaceous earth around your whole yard when it is hot and dry and it will knock down the chigger populations and can even eradicate chigger populations. Keep in mind that you will need to reapply after each rain event. 

If you bring chiggers into the house with you, do not fear, they will die off in a couple of hours without their natural environment!

Fleas outside: If you have wildlife like deer, possums, and raccoons, that occasion your yard, they can bring fleas to your yard. That said, fleas do like taller grasses, so if you keep your yard cut, this will help in the fight against fleas as well. 

If you have fleas inside, I’d recommend checking out our article on Expert Advice on Flea Control. Otherwise, do not use diatomaceous earth on the inside for fleas. Simply vacuum several times per day for a couple of weeks, and this is the most natural treatment available.

Anthills: Sprinkling some diatomaceous earth over anthills and ant nests can be a great way to kill off their colonies. It will not kill them all off, as the queen typically stays underground, but it will help kill off hundreds of worker ants, which would over time kill off the queen if she has no food. Keep in mind, like other yard treatments, this would need to be done after each rain event.

Garden Pests: Because food-grade diatomaceous earth can be ingested, there is no threat against it for using it in food gardens and herb gardens. It can certainly be used in flower gardens as well. From ants to earwigs, to any pests that can eat your crops.

If you’re wondering how much diatomaceous earth for plants, you can add diatomaceous earth to the soil as there are properties that plants may like, but for the sake of pest control, we are only talking about garden pests. If you have fungus gnats hatching in the soil of your plants or potted plants, you can sprinkle a thin layer over the soil at the base of the plant to help kill off the fungus gnats. 

Overall, diatomaceous earth provides an eco-friendly, non-toxic solution for managing a variety of yard pests, utilizing its unique physical properties to effectively control and eliminate insects that come into contact with it.

If you are wondering how to use diatomaceous earth for pest control in garden or how much diatomaceous earth for plants, the answer may vary based on the plant and the pest issue you are dealing with. It is always best to contact a pro prior to application: 651-342-9489.

8 Serious Concerns to Consider Before Use of Diatomaceous Earth

While diatomaceous earth is generally considered safe for use in various applications, it does have some potential negative side effects, particularly when not handled properly. Here are some of the main concerns.

Respiratory irritation, issues, and disease. 

There is always an inhalation risk of breathing in diatomaceous earth. The dust can irritate nasal passages, throat, and lungs. Moreover, breathing in high levels of diatomaceous earth may lead to more and more serious respiratory issues, especially for individuals with pre-existing respiratory conditions already, like asthma.

A more serious concern is a disease called silicosis. While food-grade diatomaceous earth contains very low levels of crystalline silica, prolonged exposure to especially the industrial-grade diatomaceous earth, which can contain higher levels of crystalline silica, can lead to silicosis. Silicosis is a lung disease caused by inhaling fine silica dust. 

Skin and eye irritation and issues. 

Diatomaceous earth can cause dryness and irritation if it comes into contact with skin for extended periods.

If diatomaceous earth gets into contact with eyes, it can cause irritation and discomfort. If this happens, individuals are advised to rinse out their eyes for several minutes. It is advised to wear protective eyewear during application.

Dryness and dehydration issues.

Diatomaceous earth is designed to dehydrate things, and this means skin, eyes, and any other things it comes into contact with. Diatomaceous earth’s desiccating properties can lead to dryness in the skin and mucous membranes if there is significant contact.

Environmental Concerns.

Light sprinkling applications are always advised. Diatomaceous earth is sharp and abrasive to little insects, this includes the ones we like and the ones we do like, like honeybees. So be careful where you are placing it and how much you are applying.

Digestion issues. 

Please be aware of the difference in food-grade and industrial-grade diatomaceous earth. Only food-grade diatomaceous earth is labeled safe for consumption by humans and animals. If you ingest industrial-grade diatomaceous earth, it can be harmful to your digestive system and overall health due to the higher levels of crystalline silica and other impurities.

Pets’ health issues.

If you have pets, be extra cautious where you apply diatomaceous earth. This is a reason I never recommend indoor application of diatomaceous earth: because pets are low to the ground and are often curious, smelling everywhere they go. If pets, especially if they have respiratory conditions, breathe in diatomaceous earth they can get damaged lungs and nasal cavities just like we can.

Top 4 Precautionary Measures You Can Take When Applying Diatomaceous Earth

There is an endless list of things to do in this life to take care of, but none more important than your health. Here is a list of 4 precautionary measures you can take when applying diatomaceous earth to help keep your health, your kids’ health, and your pets’ health.

  1. Wear protective gear. Be prepared of the adverse affects of diatomaceous earth and plan accordingly. Use a mask or respirator and wear protective eyewear and gloves when applying diatomaceous earth to prevent inhalation, eye contact, and prolonged skin exposure.
  2. Apply carefully. Knowing the warning signs and the best places to apply diatomaceous earth can help immensely when using diatomaceous earth. Knowing that using too much can cause issues and not help your pest situation anymore, will help you use the correct amount. Knowledge is power. For the best results, use a puffer or an applicator for the best, most targeted application.
  3. Keep out of reach of kids and pets. For kids and pets, I pretty much never recommend self-treatment when it comes to pest issues. You simply want to make sure to use quality products that are widely tested and approved and certified safe. I would absolutely suggest storing the diatomaceous earth in a cool, dark place and in a secured storage container, so kids and pets cannot come into contact with it.
  4. Be careful with ventilation. If you do use diatomaceous earth on the inside of your home (though I wouldn’t recommend it), make sure it is in a place where the fan, A/C, or heater aren’t going to kick it up into the air. You need to make sure to just treat the cracks and crevices to do the trick!

By taking appropriate precautions, the potential negative side effects of diatomaceous earth can be minimized, allowing for safe and effective use in pest control and other applications.

3 Little Known Facts About Diatomaceous Earth

  1. It is not harmful to fish or birds. The silicon dioxide found in diatomaceous earth can play an essential role in keeping chickens’ bones strong and many use it as a supplementary item to their chickens’ diet. Get Strong Animals ensures diatomaceous earth does not harm her chickens at all either!
  2. It can be known to increase the risk of lung cancer. In a lab study, mice that were forced to breathe in diatomaceous earth saw an increase in lung cancer. This is why I always advise folks to use the utmost caution when applying any sort of pesticides or DIY/natural products themselves.
  3. It does not increase the amount of silica found in the body.  In a study the silica of the diatomaceous earth ingested was present in waste and not absorbed into the body. This has nothing to do with pest control; I just thought it was interesting. Still, be careful upon application. You can learn more, if you like, at National Pesticide Information Center.

Diatomaceous earth becomes inactive. It is designed to absorb moisture, which is how it works in pest control. It is abrasive and cuts the bugs as they walk over top of it, but then it drains the bugs of its vital fluids and absorbs them. If a lot of water gets on the treatment area, diatomaceous earth becomes inactive. The diatomaceous earth we buy at the store has been processed, so it is most likely not reusable.

Yes, you can sprinkle diatomaceous earth around the outside of your house! It is a great preventative pest control method for creepy crawlies that may try to enter your home. As stated previously, we never recommend interior use of diatomaceous earth.

Yes, it is harmful to breathe diatomaceous earth. Diatomaceous earth can irritate the lungs. If your lungs are already compromised, it can cause illness or infection. In some cases, prolonged exposure can cause a disease called silicosis. Read more in our section above called 8 Serious Concerns to Consider Before Use of Diatomaceous Earth.

If you’re wondering how often to apply diatomaceous earth for bed bugs, you should not apply diatomaceous earth for bed bugs. You should call a professional exterminator to use a qualified chemical product to eradicate bed bugs. 

Self-treatment of bed bugs using diatomaceous earth can take several weeks to several months or more to get rid of bed bugs, best-case-scenario. This adds extra stress and trauma to an already traumatic situation. 

The diatomaceous earth would need to be applied in all the right areas, and they would have to walk over top of it. In order to do this, most folks don’t have the expertise to eradicate bed bugs on their own.

If you’re wondering where you can buy diatomaceous earth for bed bugs, I would NOT recommend it.

Licensed and professional pest control exterminators are educated to know all about insects and rodents, what their habits are, what their life-cycle is, where they like to travel, etc. Because diatomaceous earth could only be placed in the areas you see the pests, but the pest source could be hidden in the wall, for example, the diatomaceous earth would not solve the whole pest issue.

Licensed pest control exterminators are educated on chemical products that are routinely tested and modified and adapted to be the most effective method of pest eradication and control. Because the chemical products come in concentrated form, any diatomaceous earth placed would negate the professional products used. That is why we always have folks who have used diatomaceous earth clean it up upon hiring us.

Diatomaceous earth is deadly to insects that walk over top of it due to its sharp, abrasive edges that cut the insect and the absorbent component that draws fats and oils out of the insect, essentially killing it. Diatomaceous earth is only deadly to insects that walk over top of it and it will not solve the whole pest issue.

They also breed rapidly, so using diatomaceous earth to treat for roaches would be a losing battle.

No, bugs do not eat diatomaceous earth. Bugs would walk over it, like it were dirt, but really it is microscopic abrasive shards of fossilized algae that kills them by cutting them and absorbing their fats and oils.

Food-grade diatomaceous earth is the best option if you are using diatomaceous earth for pest control. We recommend storage in the garage, on a shelf, or in the basement/cellar on a shelf. You can keep it in the bag it came in or transfer it to a storage container.
